Final answer:
In Windows 8.1, Microsoft brought back the Start button and the option to boot directly to the desktop, features that were previously removed in Windows 8.0.
Step-by-step explanation:
The feature that was removed in Windows 8.0 and then brought back in Windows 8.1 was the Start button, which provides quick access to apps, settings, and files. After significant user feedback, Microsoft decided to restore this familiar element to improve the user experience. Another notable reintroduction in Windows 8.1 was the option to boot directly to the desktop instead of the Start screen, addressing one of the major criticisms from desktop and laptop users who preferred the traditional desktop experience.
